Has anyone done a table of what fuel consumption to expect at what constant speed for what engine and transmission?  Apologies if they have, I had a look in the archives and couldn't see it.   

My 2.6 manual Elite seems to drink noticeably more than my old 2.5 manual Reflection.      I'll do a test run, say 60mph on cruise for a flatish quiet motorway stretch and the return journey to average out any gradient. If anyoen has done anything similar let me know and I'll replicate it.

I have tested the 'range' function, twice on my 2.5 and once on the 2.6.  The 2.5 ran out at exactly 0 miles range, the 2.6 went almost 1 mile after zero appeared. So I trust the computer for accurate fuel consumption figures.

It's a different car - but my '95 elite estate (3.0l) with the cruise set to 70 seems to average about 33mpg

**If you look in your handbook near the back there's a consumption table for all the models at set speeds

Brave chap, you must be confident in the cleanliness of your tank(s).

i'm currently doing the ''albs'' test. i filled to the brim (first click), then doing some miles (prob about a hundred), refilling to the first click to see what it has consumed during those 100 miles and working out the MPG from there.

i dont know of a way of checking against various engine speeds but this is a test based on purely ''urban'' driving.

Modern, plastic tanks don't break up internally like the old metal ones used to

I think the "sludge in tanks" theory is just a myth to be honest, having dropped the diesel tank on a 140k 2.5TD to find it clean as a whistle, i can see any issues.

As LD says, modern plastic tanks don't corrode, the fuels are much cleaner, we found nothing at the bottom of the tank

What about any rubbish that might come from the petrol stations underground tanks

Possible, but then again I don't use petrol 

But seriously their tanks would have to be very low, I bet stations that have been re-done are also plastic or very very thick metal.

Like I say, 140k TD, had nothing in the tank

Very rare for them to get that low... They normally stop delivering fuel before they reach the bottom. They also have filters and screens in line to the pumps

I've seen inside a lot of fuel tanks in the last year and not yet seen one with sludge/crap in it

All well and good, but to get a real average, and as a result the reality over many different styles of driving, you need to do this test over a few tank fulls, not just 100 miles.

Agreed,only ones I've seen silted up has been where the filler pipe has corroded and let road debris in

[Webby the Bear]

if anyone's interested....

did 99.1 miles and then topped up to the first click and it took 23.06 litres.

SO after the calcs are done...

Around town i'm getting 19.5 miles to the gallon. this anything to be concerned about or should we simply re-review our driving styles?

The car does have a fuel filter.  Maybe the first time was brave but after 2 times with no problems its not really base jumping is it.  Any stuff in the tank that sticks to the bottom and doesn't get shaken up in normal driving would have to be depleted uranium.

That's just a little less than what I get on a long unspirited run
